Morris Ketchum (February 1796 – January 1, 1880) was an American banker and financier of the 19th century. In 1832 he partnered with Thomas Rogers and Jasper Grosvenor to form the manufacturing firm of Rogers, Ketchum and Grosvenor; this firm eventually grew into Rogers Locomotive Works, the second most popular steam locomotive manufacturing company in North America.
Ketchum was also a director of the Illinois Central Railroad. During his time on the board, he was able to funnel many of that railroad's locomotive orders to Rogers.
Morris Ketchum, with his son Edward B. Ketchum, led the financial firm of Ketchum, Son and Company in New York City. Edward was later found to have embezzled nearly $2.5 million to cover his losses in the 1860s; it was Morris's good reputation that kept the public from suspecting Edward of embezzlement for a time.
